/**
* The ParticleContainer class is a really fast version of the Container built solely for speed,
* so use when you need a lot of sprites or particles. The tradeoff of the ParticleContainer is that advanced
* functionality will not work. ParticleContainer implements only the basic object transform (position, scale, rotation).
* Any other functionality like tinting, masking, etc will not work on sprites in this batch.
*
* It's extremely easy to use :
*
* ```js
* let container = new ParticleContainer();
*
* for (let i = 0; i < 100; ++i)
* {
* let sprite = new PIXI.Sprite.fromImage("myImage.png");
* container.addChild(sprite);
* }
* ```
*
* And here you have a hundred sprites that will be renderer at the speed of light.
